PAPER CONTAINER STRUCTURE AND END CLOSURE THEREFOR Filed Dec. 13, 1945 Patented Dec.l1`8, 1945` PAPER CONTAINER STRUCTURE AND END CLOSURE THEREFOR James H. ONeil, Syracuse, N. Y., assignor to Convtinental Can Company, Inc., New York, N. Y.,

a corporation of New York Application December 13, 1943, Serial No. 514,129- 1 Claim. (Cl. 22S-'5.5)

'I'his invention relates broadly to paper containers and more particularlyto the manufacture of novel closure members connected with thecon-A tainer body to close the ends thereof.

One of the objects f the invention is t0 provide an inexpensive paper or fiber container which is liquid tight and strongly constructed so that the possibility of leakage in handling is substantially eliminated. l

Another object of the invention is to provide a paper container which is inexpensive to manufacture and which may be manufactured on existing machinery.

It is still another object of the invention to provide a paper container with a treated-inner lining which is impervious to liquids containing solvents, such as paint. A further object*v of the invention is to provide a container wherein onev or more slip-fit covers are provided at one orboth ends of the container body, and wherein a heavy reinforcing disc is in- .serted in the slip-t-cover tov reinforce the same.

' It is sull a further object of the invention to provide areinforced cover for a paper container which may bereadily opened, and tov provide an additional slip-llt cover 'for reclosing the container in the event all of the contents are not used at one time.

Withl the above andother objects in view that lwill hereinafterappean'the nature of the invention will be more fully understood by following the detailed description, the appended claim and the several views illustrated in the accompanying drawing.

In the drawing: Figure 1 is a sectional view of a container illustrating one embodiment of the invention.

Figure 2 is an enlarged partial sectional view of one corner of the top of the container illustrated in Figure l, the reclosure cover being removed. y

Figure 3 is a side view of the exterior of the container shown in Figure 1.- y

Figure 4 is a sectional view of a container illustrating a second possible embodiment ofthe invention.

Figure 5 is a side view of the container shown In Figure 4.

The two species of the invention herein disclosed embody the same generic invention, and a claim covering the two species generally is included herein. l s

Referring' specifically to the drawing for a detailed description of the invention, and more par ticularly to Figures 1, 2 and 3, numeral I0 designates generally a paper container comprising a body member I I having a top closure generally indicated at I2 and a bottom closure formed by turning the end of the wall II, as at I3, over an in contact withv the inserted cup-likeend ember 2|, andthe turned end I9 is crimped at 23 with a suitable tool to provide a liquid-tight Joint at the top of the container. The top reinforcing disc 22 is preferably scored at 24 so that a cuttingl instrument may be inserted to remove the disc and gain access to the contents of the container. The internal chamber deiining body wall and end closure portions of the container are provided with suitably-treated inner surfaces 25 which are impervious to materials containing solvents such as may be present in paint or the like.

Usually, contained materials are not all used up at the time of the initial opening of the container, and,'in order to reclose the container,-a reclosing cover 26 is provided which slips over the outer surface of the glued, slip-fit cover I1. The reclosing cover 26 is also formed by a collar member 21 which is turned over at 28 and crimped at 29 to retain a cup-like, inserted end member 30 in position.

Referring now to Figures 4 and 5, this container comprises a fiber or paper body member 32, andthe top and bottom closure members 33 and 34 are substantially the same asl those shown in Figures 1, 2 and 3. Thus, further detailed description of these end closures is thought to be unnecessary. However, in this embodiment, the heavy reinforcing-disc at the bottom of the container is scored at 35 and the top reinforcing disc is left unscored. In this embodiment a slip-llt cover 36 is placed on the bottom of the container and is constructedA in the same manner as the slip-fit reclosing cover 26 shown in Figure 1. When this container is to be opened, itis inverted, the reclosing cover 36 removed, a knife inserted in the scoring 35, and the disc and end member removed. YTlie'reclosing cover. 36 is then replacedif all the contents of the Acontainer are not used.

A ,second heavy reinforcing disc 22 is placed which is impervious to paint. v

From the foregoing, it will b `apparent that an improved paper or fiber contai er has been proto the nature of the product to be packaged and the desire of the manufacturer.

Changes and modifications of the invention may occur to those skilled in the art, but the invention comprehends all such variations of the herein described structures as come within the spirit and scope of the appended claim.

What is claimed is:

20 opening of thecontainer.

tainer also are provided with a suitable treatment A fiber container comprising a cylindrical open end body member, a bottom end attached to said body member and a top end closureI for said be `ly member including a collar glued to the outer face oi' the body member and projecting above the end thereof, a cup-shaped member inserted in said collar and dimensioned solas to` extend over the end of the body wall and contact with the inner face of the collar, a heavy reinforcing disk disposed within said cup-shaped member and dimensioned so as to extend over the body Wall and abut against the cylindrical wall of the cupshaped member for clamping the same against the inner surface of said collar, said collar being turned over the cylindrical wall of the cupshaped member and crimped into engagement with the inner face thereof and the outer peripheral portion of said heavydisk, said disk being scored to permit the rupturing thereof for the JAMES H. ONEIL.
